A little Purple Chalcedony for this Wednesday.
Chalcedony is a microcrystalline variety of silica (quartz) known for its waxy luster and wide range of colors, encompassing gemstones like agate, jasper, carnelian, and onyx, historically used for tools, carvings, and jewelry due to its hardness (6.5-7 Mohs) and durability, forming globally in various rocks and known for symbolic meanings related to communication and peace. A Silicon dioxide, made of intergrown quartz and moganite crystals. Translucent to opaque, waxy luster, often grayish-blue, white, brown, or pink, but can be dyed. Early humans used it for projectile points, knives, and containers. Popular for carvings, beads, and decorative items due to its beauty and durability. Believed to promote courage, communication (Throat Chakra), and peace.

Some good old Biggs Area Jasper for this Monday Morning. Not from Biggs Junction proper, but nearby. Heaven knows the Facebook rock police would jump my post if I called it true Biggs.

Biggs Area Jasper refers to a prized scenic picture jasper found near Biggs Junction, Oregon, known for its layered, landscape-like patterns in browns, ochres, and sometimes blues, formed from volcanic ash deposits. This classic Oregon stone, similar to Deschutes and Beers Mountain Jaspers, showcases geological artistry with distinct banding, rosettes, and valley scenes, though the original deposits are largely paved over.

This one turned out really nice. Most of the time you just cut a Thunderegg in half and polish the faces, well sometimes I like to take it to the next level...

This Rufus Jasper cabochon took a little more time than normal, but sometimes the same old shapes get old. For those new to Rufus Jasper, just think of it as Biggs Jasper's little sister.
Biggs jasper (and this Rufus material) is found between two of the basalt lava flows that once covered the U.S. states of Oregon, Washington and parts of Idaho. Many thousands of years passed between the individual flows, allowing life to flourish. During this time, the volcanic ash decomposed into clay and was deposited by rain water in streams and lakes atop the cooled basalt. There it mixed with silica and iron from the weathering of the then-recent igneous rocks, forming a plastic colloid.
When lava next flowed over it, the heat and pressure transformed the muddy mixture. As water escaped it in the form of superheated steam, pressure variations resulted in flexing and many short fluctuating changes, reflected in the jasper's many thin, parallel bands. The hydrothermal reaction progressed as a shock wave through the mud, removing iron from it and depositing the iron as intertwining bands of limonite. The altered rock remained plastic, and subject to local movement as a result of pressure changes. These caused the great variety of marbled, rosette-like and picture designs found in Biggs jasper.

A little bit of wood on your Monday morning... This time its Hampton Butte Green.
Hampton Butte in central Oregon is known for its colorful, gem-quality petrified wood, especially prized for its rare, vibrant green specimens, colored by copper and chromium during fossilization, alongside red, yellow, and blue hues. Originating from the Oligocene epoch (20-30 million years ago) in the John Day region, this wood often features distinct wood grain, bark texture, and agate/jasper interiors, making it highly sought after by rockhounds for lapidary and collection.
Key Characteristics:
Colors: Predominantly green (due to copper/chromium), but also red (iron), yellow, blue, and brown/white mixes.
Quality: Often gemmy, with well-preserved cellular structures, rings, and sometimes bark texture.
Composition: Can be 'jasperized' or 'opalized', with agate/opal cores.
Age: Around 30-40 million years old (Oligocene).
Where to Find It:
Located in central Oregon's John Day country.
Found on both public (BLM) and private lands.
Rockhounding Tips:
Look in tailings piles from other diggers for good tumbling material.
Scout the surface for easier finds or dig pits for more significant finds.
High-quality pieces can be valuable, especially larger, gemmy green ones.
